TRAoToR ATTACHMENT.

Application filed September 18, 1925. Serial No. 57,160.

One object of'our present invention is the provision of an attachment through the medium of which plows, lister disks and the like may be carried behind a tractor, and

. this in such manner that the ground working elements, plow lister disks or the like, may be expeditiously and easily raised and lowered by the tractor driver with but little effort on his part. A

Another object of the invention is the provision of an attachment of the character.

described embodying simple, eflicient and durable means, whereby the plow, lister disks and the like may be adjuste'd'laterally. and adjustably fixed 'soas to promote the efficiency of the plow and lister disks'when the tractor is in inclined position.

Other objects and practical advantages of the invention will be fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and forming part of this specification, in which 1 Figure 1 is a view showing the rear portion of a tractor with one of the wheels thereof removed, and with our novel 1 attachment attached to the tractor? Figure 2 is a top plan view ofthe same,

7 both rear wheels of the tractor being shown.

Figure '8 is an enlarged transverse section taken in the plane indicated by the line 3v3 of Figure 2, looking forwardly.

Similar numerals of reference designate corresponding parts, in all of the views of the drawings.

The tractor illustrated may be of the ordinary well known construction or of any other construction to which our improvement is applicable, and it includes a casing body 1 with lateral housings 2 and rear wheels 0- onthe casing body 1 and is designated by t.

Fixed on the right hand housing 2 of the tractor is a collar 5, and fixed with respect to the said collar is a segmental rack 6 with which is adapted to cooperate the'detent 7 of a hand lever 8 that is fulcrumed at 9, and is designed for the vertical adjustment and vadjustable fixing of the body 10 by which a plow 11 and lister disks 112 are carried. The lister disks 12 are connected directly to opposite sides of a rear enlarged The driver seat of the tractor is mounted portion 13 of the body 10, while the plow 11s is carried bya beam 14; fixedly connected to'standards 15 and 16 on the body 10,the said beam having open portion '17, Figure 2, and also having a longitudinal central bar 18. The open portion 17 andcentral bar 18 are fixed with respect to each other as suggested in Figure 2 of the drawings,

Pivotally connected at 19 to the bar 18 of the beam 14: is a link 20, the said link 20 being connected at its forward end to an arm 21 on a transverse rock shaft 22 disposed in rear of the casing body 1 and above the drawbar 23 usually provided on the said casing body. The said rock shaft 22 is piv- .otally connected at 24120 a fixed bracket 25 at one side ofthe casing body 1, and is pivotally connected at its opposite end to a bar 26 fixed toand extending rearwardly from the .collar 5. It will also be noted that the rock shaft '22 is provided adjacent to the right hand wheel of the tractor with an arm 27.- This arm 27 is connected by a rod28 with the hand lever 8, and by virtue of the construction described it will be understood that when the hand lever 8 is moved forwardly, the shaft 22 will be rocked, and the body 10 and the plow l1 and lister disks 12 will be swung vertically. This provides for the vertical adjustment of the plow 11 and lister disks l2, and the detent 7 in cooperation with the segmental rack 6 provides for,

the adjustable fixing of the plow 11 and lister disks 12 against casual vertical move ment all of which will be better understood when it is stated that the body 10 is carried by a transverse bar 30'which has depending arms 31 at its ends pivotally connected at 32 to hangers 33 having converging portions connected at 3 1 to opposite sides of the casing body 1, the said hangers 33 being each provided with a plurality of apertures'35 for the adjustable connection of said arms 31 at points below the hori.-- zontal plane of the rear axle of the tractor.

As best shown in Figure 2 the rod 28 is extended loosely through a Ueshaped bracket LOon the upper'end. of the arm 27 and said -rod 28 is provided in rear of the bracket abutment 212 on rod 28 is a coil spring 43. By virtue of this construction it will be manifest that the rock shaft 22 and the parts connected therewith are capable of upward movement to a limited extent with respect to the rod 28, such movement being cushioned by the spring and being designed to enable the plow 11 and lister disks 12 to more readily ride over obstructions in their paths.

For the lateral adjustment of the body 10, the plow 11 and the lister disks 12, the body 10 is provided with a forward T-head 50, and the said T-head is pivotaily connected by a longitudinal bolt 51 to a block 51 which is secured to the transverse bar 30 so that the body 10 can be rocked laterally on the axis of the said bolt 51. Fixed to one end oil the transverse bar 30 is a segmental rack (50, and pivoted at (51 to said raeli is a cranlt lever 62 having a detent (33 for cooperation with the rack (30, the lower arm of the lever 62 being connected by a link 64 with one end of the block 51 from which it follows that by adjusting the lever 62 the body 10 may be roclted laterally on its axis for the purpose indicated, and by cooperation of the detent 63 with the rack the body 10 and plow 11 and lister disks 152 may be adjustably fixed in the late ally inclined positions in which they are placed.

It will be apparent from the foregoing that our novel attaclnnent is readily applicable to trzlctors, and that it provides for the convenient adjustment of the plow and lister disks both vertiially and laterally.

It will also be readily understood that the connection of the body 10 to the bar 30 is a detachable connection so that body having ground working, elements diil'erent from the plow 11 and the lister disks 12 may be connected to the bar 30 and to the hand lever (52, and used in lieu of the body 10 and its appurtenances when occasion demands. i

It will be apparent from the foregoing that our novel attachment is not only advantageons tor the reasons pointed out but is manifestly simple in construction and reliable in operation. and generally well adapted to withstand the usage to which tractor attachments are ordinarily subjected.

In order to lend increased rigidity and strength to the hangers 83, we connect to the said hangers 83 in fixed manner a transverse bar which bar T0 is fixed at 71 to the usual d 'awbar 72 provided on the tractor body 1.

lVe have specifically described the preferred embodiment of our invention in order to impart a full, clear and exact understanding of said embodiment. e do not desire, however, to be understood as confining ourselves to the specific construction disclosed.
